Important causes of blindness in two eyes
There are many causes of blindness. Three important ones are:
This is the cause in 20% of cases where children are affected. A cataract is a clouding of the lens inside the eye. In children it may be due to hereditary causes, or due to infections like rubella during pregnancy. Whatever the initial cause, blindness due to cataracts can be prevented by early detection and treatment.
This is the cause in 20% of cases affecting children. Retinopathy of prematurity is the scarring of the retina at the back of the eye that may occur when high levels of oxygen are administered to premature babies. Blindness due to retinopathy of prematurity can be prevented by early detection and treatment.
This is the cause in 10% of cases affecting children. Corneal scarring refers to scarring of the window in the front of the eye. It may be due to infections, Vitamin A deficiency, and the use of harmful traditional eye medicines. Blindness due to corneal scarring can be prevented by early detection and treatment.
There are two basic types:
This is when the body does not produce enough insulin and a person must take medication or inject him/herself. People normally complain that they only see certain parts of an object and they also complain of having blurred vision.
Pressure builds up and results in vision field loss. Sometimes if the pressure cannot be controlled it might end up in blindness. Eye drops can be prescribed or they can operate to try and drain the fluid.
This is an inherited eye condition. People normally complain of loss of peripheral vision and the person ends up having tunnel vision. They function quite well in daylight but are blind at night.
Important causes of blindness in one eye.
These can result from accidents caused by a variety of objects, such as sticks, stones, BB pellets and fireworks. Children should be discouraged from playing with items like these.
This may occur where children have a squint (when eyes are not straight), or sometimes if the child needs glasses. If neglected, this condition cannot be treated.
If you think your child has a vision problem, don’t delay, get their eyes tested by a professional.
